For the past 15 years, Mozilla has been a pioneer in web innovation and creativity, putting their weight heavily behind open standards and development. Their Firefox web browser helped create the current competition on the market, and they're hoping that the new Firefox OS can do the same for mobile devices.

Towards the end of last month, Mozilla took the wraps off their open-sourced Firefox OS by introducing a pair of developer devices dubbed Keon and Peak. Now at the Mobile World Congress in Barcelona, the company announced that they've joined forces with partners across the globe to bring the OS to the retail market. The first wave of Firefox OS powered devices will be made available in lower-income countries, including Brazil, Columbia, Hungary, Mexico, Montenegro, Poland, Serbia, Spain and Venezuela.

Mozilla introduced a pair of those phones over the past couple days, including the Alcatel One Touch and ZTE Open, which target buyers in emerging markets and developing countries. One of Firefox OS's main features is HTML 5, which allows web-based apps to be available across devices as well as enabling developers to use different methods for payment. Those features can be seen in the video below, along with a full walkthrough of the ecosystem.
